Holly Madison has opened up about her time living at the Playboy Mansion.
The model, now 41, resided at the lavish property from the early 2000s until she and Hugh Hefner split in 2008.
The star is set to appear in A&E's docuseries titled Secrets of Playboy and will dish out what made her time there a challenge.
Watch Holly Madison open up about her time in the Playboy Mansion:
In a preview for the 10-hour exploration into the once-heralded Playboy empire - set to debut January 24 - Madison exposes the mental and emotional anguish she endured as a Playmate from 2001 to 2008 at the hands of Hefner - who died of sepsis in 2017 at age 91.
"I felt like I was in the cycle of gross things and I didn't know what to do," the former Playboy pinup and ex-girlfriend of the late Hefner says in a new clip for the series.
"I got to a point where I kind of broke under that pressure and being made to feel like I needed to look exactly like everybody else," she added.
Elsewhere in the clip, Madison revealed that she wasn't the only Playmate to experience Hefner's sinister side.
"Hef pretended that he wasn’t involved in any hard drug use at the mansion, but that was just a lie," says Hefner’s ex Sondra Theodore, a Playmate from 1976 to 1981.
"Quaaludes down the line were used for sex," she said. "Usually you just took a half [of a Quaalude]. But if you took two, you'd pass out.
"There was such a seduction, and men knew that they could get girls to do just about anything they wanted if they gave them a Quaalude."
Hefner's former secretary and executive assistant corroborated Theodore's claims of the tycoon's penchant for drugging women.
"Quaaludes were what we called leg-spreaders. That was the whole point of them," Lisa Loving Barrett says in the clip. "They were a necessary evil, if you will, to the partying."
"We would have prescriptions in some of our names," Barrett added. "There were prescriptions in Sondra’s name, in Hef's name and in my name and Mary's name. We kept a desk calendar that would say 'Lisa's Q' or 'Hef's Q' or 'Sandra's Q.’'"
Barrett said the mansion's copious amounts of illegal substances "enabled four or sometimes five prescriptions for the same medication to feed the machine."
